UNITED STATES PATENT OFFICE.

GEORGE I. STRACHAN AND J LEE STRACHAN, \OF MUIR, MICHIGAN.

SHINGLE.

Application filed September 23, 1921.

T 0 all whom it may concern:

Be it known that we, Gnonen I. STRAOHAN and J LEE STRAGHAN, citizens of the United States, residing at Muir, in the county of Ionia and State of Michigan, have invented certain new and useful Improvements in Shingles, of which the following is a specification.

This invention relates to shingles or roof coverings which require a structure which will effectually exclude rain, snow and the like, and which at the same time will be comparatively of low cost and simple of application.

The object of this invention is to provide a shingle composed of a composition, and

7 preferably laminated structure, which is substantially flexible in the direction of its width but substantially rigid in the direction of its length.

A further object is to provide a composition shingle with means for supporting and strengthening it in the direction of its length.

Referring to the accompanying drawings forming a part of this application- Figure l is a top perspective view of one form of our shingle illustrating its structure in transverse section;

Figure 2 is a vertical sectional view of the shingle on the line 2-2 of Figure 1; and

Figure 3 is a View similar to Figure 2, but illustrating a different form of supporting and strengthening strip.

The shingle shown in the accompanying drawings by the numeral 2 consists of preferably rectangular pieces of sheet material of a size and shape substantially similar to the usual asphalt shingle, although its shape and size may be readily altered. to suit the taste of the builder or the conditions incident to its use and application and comprises a sheet of flexible material such as burlap, or heavy cloth or roofing felt having a saturation and coating of asphalt or other waterproofing; materials, upon which may be laid, while the tar is still viscous, a covering of Serial No. 502,703.

colored sand, or finely broken slate or stone, which latter is rolled into the tar or like waterproof and sticky material so that it is firmly embedded therein, thereby provid ing a surface which is not only waterproof but very ornamental.

The shingle is provided with longitudinal corrugations L pressed into the shingle before the composition has become set, the under or lower portions of said corrugations being provided each with a strengthening wooden strip 6 secured in position by means of nails or staples 8, which at the same time fasten the shingles to the roof boards.

These wooden strips 6 not only provide strengthening or reinforcing means which extend. the full length of the shingle, but also provide a means whereby the shingles may be laid over open roof boards. Further, these strips support the corrugation and prevent crushing or collapsing of the shingle, during laying, should the workman step or apply any weight or pressure thereon.

In Figure 3, the wooden strips 6 are substituted by metal inverted trough-shaped strips 8 which are suitably secured in the corrugations by fasteners 10 and function precisely as said wooden strips 6.

Having thus described our invention, what we claim as new and desire to protect by Letters Patent, is:

A shingle comprising a flexible sheet of material provided with spaced longitudinal corrugations therein, reinforcing strips conforming to the configuration of said corrugations and arranged therein, the. bottom faces of said reinforcing strips adapted to extend flush with the lower faces of the portions of said shingle formed between said corrugations therein, and fastening means extending through said corrugations and through said reinforcing strips and adapted to be driven into roof boards.

In testimony whereof we afiix our signatures.

GEORGE I. STRACI-IAN. J LEE STRACHAN.
